slapos.recipe.build 0.4

Flexible software building recipe.

slapos.recipe.build

Important notice

This is totally experimental recipe for fully flexible software “build”.

Examples

Recipe to build the software.

Example buildout:

[buildout]
parts =
  file

[zlib]
# Use standard configure, make, make install way

  workdir = guessworkdir(extract_dir)
  self.copyTree(workdir, "%(location)s")

TODO:

• add linking suport, buildout definition:

slapos_link = <relative/path> [optional-path]

can be used as:

[file]
slapos_link =
  bin/file
  bin/file ${buildout:bin-directory}/bin/anotherfile

Which will link ${file:location}/bin/file to ${buildout:bin-directory}/bin/file and ${file:location}/bin/file to ${buildout:bin-directory}/bin/anotherfile

Pure download

[buildout]
parts =
  download

[download]
recipe = slapos.recipe.build:download
url = https://some.url/file

Such profile will download https://some.url/file and put it in buildout:parts-directory/download/download

filename parameter can be used to change destination named filename.

destination parameter allows to put explicit destination.

md5sum parameter allows pass md5sum.

mode (octal, so for rw-r–r– use 0644) allows to set mode

Exposes target attribute which is path to downloaded file.

Notes

This recipe suffers from buildout download utility issue, which will do not try to redownload resource with wrong md5sum.
